All releases of Plone CMS

Release Notes: The project has seen a number of releases up to this one,
which fixes several security problems
and provides significant improvements,
like HTML5 support,
a new collection type,
official support for Python 2.7,
and support for Diazo out of the box (plone.app.theming).

Release Notes: This release works with the fully eggified Zope 2.12 and Python 2.6, so you can finally dispose of Python 2.4. It's significantly faster than Plone 3. It has a greatly improved default theme. Support for Zope3 style development methods has also improved.

Release Notes: This release includes Zope 2.10.11, which fixes a potential XSS issue in the default error page in Zope. An important issue in the base2 JavaScript library would cause the Java plugin to be invoked if you had Java on your computer and were using Firefox 3.5, since there is a "magic" variable that starts the Java VM when accessed. This has been fixed.

Release Notes: Many bugfixes as well as performance improvements and better and easier APIs. Plone is now fully eggified and has installers for all major platforms. Plone 3.3.x should be backwards-compatible down to Plone 3.0.x, so older products should continue to work.
